I simply relocated right into a new house (well, actually it"s old - 1920). We do not have a garbage disposal and also was interested in in having actually one installed so I dubbed a ptimber. He approximated $650-750 saying that the electric wiring would certainly be the primary expense bereason the electric demands to be run straight to the circuit breaker. Is that right? Perhaps I have the right to execute the wiring myself?



Yes, you"ll require a 20 Amp 120V outlet via simply the disposal on it. I do not see why you shouldn"t be able to wire it up yourself.

Something else to think around - is your residence on a septic tank or a drain system? Some city regulations don"t enable a garbage disposal on a septic tank. Ours is type of kludged through the switch under the sink bereason it was an after-inspection add-on to the home when it was developed. At least that"s what the residence inspector told me once I asked him about it.


How updated is your wiring? In an old house, it might still have actually knob and tube wiring. If this is the case then I wouldn"t desire to mess through wiring up a disposal.

However, if the wiring has actually been redone with modern stuff, then its pretty easy. I put one in my 1920s residence (through updated wiring) previously this year.

The primary trouble I had actually is that every spot on my breaker box was already complete. (See question I asked about this here.) Code does in fact require the disposal to have its very own circuit, however for me this was tough choice. Instead I simply spliced into the existing kitchen circuit.

By my calculations, a 1/4 HP disposal (which is really all you need) will attract about 1.5 Amps of present.

.25 HP = 186 Watts 186 Watts / 120 V = 1.5 Amps

I calculated the max power draw of all the kitchen appliances plus the new disposal, and also it was well under the 20 Amp max of the circuit. It appears silly to dedicate a whole circuit to an appliance that shouldn"t attract over 2 Amps.

A double check of the specs on my 1/4 HP disposal suggests it pulls up to 9 Amps! Don"t do what I did. Put the disposal on its very own circuit.

$650-$750 is a lot to pay. If you"re home"s wiring deserve to handle it, it"s somepoint you have the right to do yourself for about $150 in materials and also a few hrs of work.
